Intraspecific trait variation of woody species reduced in a savanna community, southwest China

open access: yesPlant Diversity, 2022
Plants deploy various ecological strategies in response to environmental heterogeneity. In many forest ecosystems, plants have been reported to have notable inter- and intra-specific trait variation, as well as clear phylogenetic signals, indicating that

Individualistic responses of forest herb traits to environmental change [PDF]

open access: yes, 2020
Intraspecific trait variation (ITV; i.e. variability in mean and/or distribution of plant attribute values within species) can occur in response to multiple drivers.

Impacts of allopolyploidization and structural variation on intraspecific diversification in Brassica rapa [PDF]

open access: yesGenome Biology, 2021
AbstractBackgroundDespite the prevalence and recurrence of polyploidization in the speciation of flowering plants, its impacts on crop intraspecific genome diversification are largely unknown.Brassica rapais a mesopolyploid species that is domesticated into many subspecies with distinctive morphotypes.ResultsHerein, we report the consequences of the ...

Anthropogenic change decouples a freshwater predator’s density feedback

open access: yesScientific Reports, 2023
Intraspecific interactions within predator populations can affect predator–prey dynamics and community structure, highlighting the need to better understand how these interactions respond to anthropogenic change. To this end, we used a half-century (1969–

A direct comparison of the effects and mechanisms between species richness and genotype richness in a dominant species on multiple ecosystem functions

open access: yesEcology and Evolution, 2021
Both species (interspecific) richness and genotype (intraspecific) richness of dominant species have significant effects on ecosystem functioning directly or indirectly by regulating plant community functional structure.

Intraspecific Variation in the Rates of Mutations Causing Structural Variation in Daphnia magna [PDF]

open access: yesGenome Biology and Evolution, 2021
Abstract Mutations that cause structural variation are important sources of genetic variation upon which other evolutionary forces can act, however, they are difficult to observe and therefore few direct estimates of their rate and spectrum are available.

Time- and depth-wise trophic niche shifts in Antarctic benthos [PDF]

open access: yes, 2018
Climate change is expected to affect resource-consumer interactions underlying stability in polar food webs. Polar benthic organisms have adapted to the marked seasonality characterising their habitats by concentrating foraging and reproductive activity ...

Intraspecific divergence of diploid grass Aegilops comosa is associated with structural chromosome changes

open access: yesComparative Cytogenetics, 2023
Aegilops comosa Smith in Sibthorp et Smith, 1806 is diploid grass with MM genome constitution occurring mainly in Greece. Two morphologically distinct subspecies – Ae. c. comosa Chennaveeraiah, 1960 and Ae. c. heldreichii (Holzmann ex Boissier) Eig, 1929 are discriminated within Ae.

Assessing the Risk of Invasion by Tephritid Fruit Flies: Intraspecific Divergence Matters. [PDF]

open access: yesPLoS ONE, 2015
Widely distributed species often show strong phylogeographic structure, with lineages potentially adapted to different biotic and abiotic conditions.

Variation in wing morphology is related to breeding environment in a high‐elevation specialist bird

open access: yesJournal of Avian Biology, 2022
The morphology of bird wings is subject to a variety of selective pressures, including migration, predation, habitat structure and sexual selection.
